Dropped on this place by pure accident - managed to pick the weekend when there was a huge conference in town with 4500 delegates attending and the New York Yankees were playing a 4 series game against the Marriners so rooms were at a premium. My only complaint is I paid over the ods but all rooms were at a premium when we stayed.
The hotel is about a mile from the main city and offers a free transfer service but unless it is raining or you have mobility issues I would recommend the walk along the lake edge past the boats as the scenery is stunning.
The roms are huge and spotless and the breakfast is lovely. The cost can be a bit high but given the price of parking in Seattle and the fact that breakfast is included do go someway to evening the cost out as many hotels closer to the centre charge for both.
The staff are helpful and happy to help at anytime and the pool and gym are clean and an excellent addition.
I would thoroughly recommend this place as a base for Seattle
